Philadelphia is the largest city in Pennsylvania and the sixth-most-populous city in the United States. In 2005, the population of the city proper was estimated to be over 1.4 million, while the Greater Philadelphia metropolitan area's population of 5.8 million made it the country's fifth-largest. The city is the nation's fourth-largest urban area by population and its fourth-largest consumer media market as ranked by the Nielsen Media Research.

In the first decades of the 19th century, Federal architecture and Greek Revival architecture were dominant in Philadelphia. Frank Furness is considered Philadelphia's greatest architect of the second half of the 19th century, but his contemporaries included John McArthur, Jr., Addison Hutton, Wilson Eyre, the Wilson Brothers, and Horace Trumbauer. In 1871, construction began on the Second Empire-style Philadelphia City Hall. Despite the construction of steel and concrete skyscrapers in the 1910s, '20s and '30s, the 548 ft (167 m) City Hall remained the tallest building in the city until 1987 when One Liberty Place was constructed.

Numerous glass and granite skyscrapers were built from the late 1980s onwards. In 2007, the Comcast Center surpassed One Liberty Place to become the city's tallest building and make Philadelphia one of only four American cities with two or more buildings over 900 feet.
